However, some of my previous patches limit memblock_alloc() to the region covered by MEMBLOCK_ALLOC_ACCESSIBLE which is not quite what we want for memblock_alloc_try_nid(). So we fix it by explicitely using MEMBLOCK_ALLOC_ANYWHERE. Not that so far only sparc uses memblock_alloc_nid() and it hasn't been updated to clamp the accessible zone yet. Thus the temporary "breakage" should have no effect.
